[0.00 Fritz 5.00: 15.Bf4 b5 (15...g5 was presumably what White wanted to avoid: 16.Ne5 is the most forward-looking reply. 16.Ne5 Nxe5 17.Bxe5 Nd7 18.Bf4]

15...b5 Fritz doesn't like this much.

43.Qf8 Right idea, wrong move order. Had White not seen Black's threat, or did he consider it inevitable?
